Possible coding and scanning methods for two-dimensional position-sensing are reviewed. Encoding schemes for one type of scanning method, namely "Window-scanning", are examined in some detail.

A soccer robot system consists of multi-agents with highly coordinated operations and movements so as to fulfill specific objectives, even under adverse situations. The coordination of multiagents is associated with lot of supplementary work in advance. The associated issues are position correction, prevention of communication congestion, local information sensing in addition to the need for im...

Internet of Things (IoT) for Smart Environments (SE) is a new scenario that collects useful information and provides convenient services to humans via sensing and wireless communications. Infra-Red (IR) motion sensors have recently been widely used for indoor lighting because they allow the system to detect whether a human is inside or outside the sensors’ range. In this paper, the performance ...

This paper addresses a wildlife monitoring problem using team of unmanned aerial vehicles (UAVs) with the optimal transport theory. The state-of-the-art technology UAVs has been an increasingly popular tool to monitor compared traditional methods such as satellite imagery-based sensing or GPS trackers. However, there still exist unsolved problems how need cover spacious domain detect animals ma...

Cooperative (spectrum) sensing is a key function for dynamic spectrum access and is essential for avoiding interference with licensed primary users and identifying spectrum holes. A promising approach for effective cooperative sensing over a large geographic region is to rely on special spectrum-sensing providers (SSPs), which outsource spectrum-sensing tasks to distributed mobile users. Its fe...

Article history: Received 23 September 2015 Received in revised form 1 March 2016 Accepted 1 March 2016 Available online 2 May 2016 Spin transfer torque (STT) switching realized using a magnetic tunnel junction (MTJ) device has shown great potential for low power and non-volatile storage. A prime application of MTJs is in building non-volatile look up tables (LUT) used in reconfigurable logic. ...

Due to that the Ultra Wide Band (UWB) technology has some attractive features like robustness to multipath fading, high data rate, low cost and low power consumption, it is widely use to implement cognitive radio network. Intuitively, one of the most important tasks required for cognitive network is the spectrum sensing. A framework for implementing spectrum sensing for UWB-Cognitive Network wi...

This paper proposes a cooperative spectrum sensing scheme based on trust and fuzzy logic for Cognitive Radio Sensor Networks (CRSN). The CRSN nodes use the T-S fuzzy logic to make local decisions on the presence or absence of the primary user’s (PU) signal, and then use a censoring method to only allow the relatively reliable decisions sent to the fusion center. Utilizing a trust evaluation sch...

In this paper, a new joint speech encoding scheme based on compressed sensing was proposed. In this encoding algorithms, the compressed sensing reconstruction and PCM (Pulse Coding Modulation) were used for the speech signal encode. For the speech signal, the high frequency and low frequency coefficients can be acquired by using the wavelet transform based on the lifting scheme. For the details...

In this paper, compressed sensing (CS) theory is utilized in a medium-access control (MAC) scheme for wireless sensor networks (WSNs). We propose a new, cross-layer compressed sensing medium-access control (CL CS-MAC) scheme, combining the physical layer and data link layer, where the wireless transmission in physical layer is considered as a compress process of requested packets in a data link...
